Recently, TBEA Xi'an Electrical Technology Co., Ltd. developed 100kW, 250KTL, 500KTL ENEL and products passed CE-EMC testing, marking the new energy company TBEA brand inverters made ​​a pass to enter the Italian market, this award is the second Golden Sun, CE, TUV certified, received another breakthrough certification.

ENEL is the world's third-largest power company, is the largest of the Italian state-owned power companies, in Italy customers accounted for 87% of the whole of Italy. The test consists of internationally renowned photovoltaic testing and certification bodies - TüV Rheinland Group conducted after a five-day field test, and ultimately passed.

TBEA brand dc to ac power inverter through ENEL and CE-EMC testing, marking the new energy technology research and development company inverters elevated to a new height, but also the strength of the company's technology and product quality in a perfect display of international trade, improve the company's reputation and reputation of the company to the international road towards another solid pace.

In 2010, the PV inverter industry, the utilization of rapid gains disruptive technologies , micro-inverters and power optimizers , shipments grew more than 500%. But they still only account for PV inverters less than 1% of total revenue . Out mostly concentrated in a small volume of some of the suppliers among companies such as Enphase and SolarEdge , respectively, in micro-inverters and DC-DC power optimizers success on the market , and is currently active in the market of suppliers have more than 20, and the market is expected to grow at an annual growth rate doubled and continued until 2015 .

IMS Research expects micro grid tie inverter and power optimizers market value by 2015, more than 1.3 billion U.S. dollars . Until then, mass production can be achieved through an OEM agreement , the price of these breakthrough technologies will be significantly reduced. However, by 2015 , the average price of micro-inverter is expected to still be higher than the traditional 50% of the inverter , so the market penetration will be limited to about 6%.

Increasing the amount of supply and declining prices will drive these two ground-breaking technology. IMS Research 's PV market analyst Tom Haddon said: "The groundbreaking technology , such as off grid inverter and power optimizers claim to be able to bring many advantages, including greater gains , easy installation, and security and to improve monitoring of .

But their prices are high, and the market is relatively immature , limiting their development , especially for non-residential installation system . Outside North America , the development of micro-inverter penetration is very slow , because Europe's installers still prefer the string inverters . "

Although the development of the new inverter market in its infancy , but there are several factors that may promote or hinder its development. Some micro-inverters and power optimizers suppliers is actively consult and cooperate with component suppliers , providing component integration solutions. By 2015 , 45% and 40% of the micro-inverter power optimizer will combine with the component .

Tom Haddon said: "By working with component suppliers , micro- inverters and power optimizers providers can get a huge customer base and established sales channels , providing customers with better prices , while also providing for the component suppliers differentiated products . "

Recently, the Guangzhou Crystal Electric Co., independent research and development , production Sununo series single-phase grid-connected inverter Sununo-TL3KA/4KA/4.4K/5K passed the internationally renowned agency TÜV SÜD certification, and successfully obtained TÜV, LVD- CE and EMC-CE certificate.

      As the customer base most popular power segment products , Sununo-TL3KA/4KA/4.4K/5K has a number of advantages . The main advantage of this product is to achieve two independent MPPT control inputs , real-time tracking solar panel power and speed through precise MPPT algorithm at runtime without transformer efficiency up 98.1% , to maximize the system's generating capacity and energy reservoir .

Especially suitable for double- headed roofing equipment ( such as east and west ) . Wide input voltage range makes it suitable for small string voltage equipment . IP65 protection and a completely sealed design makes this outdoor sine wave inverter can adapt to harsh environmental conditions. This product is a device designed to provide maximum flexibility , won customers. In this year August 11 to August 13 in Guangzhou Photovoltaic Exhibition , the product will be participating experts and foreign businessmen alike.

      Throughout the certification process , SAJ Sununo-TL3KA/4KA/4.4K/5K photovoltaic inverters successfully passed all tests.
